Sorry Nicole. I am tempted to get fiddly about where you can use a power tool and where you can't, but a big part of this is the exercise of no power tools. The hole is, therefore, either made with chisels or with something that is hand powered. like this
It goes half way. Some of the videos showed having it go all the way through, while other's went only part way. I chose the latter option, since it didn't seem to be specified how far one needs to drill into the mallet head.
Nicole, no biggie, we are getting things started and it is good to sort this stuff out.
A lot of the videos and pics are not a perfect fit - but give some impression.
In this case, since we are not using glue and we are not putting a wedge into the end, we are taking advantage of the green wood shrinking around the dry stick. So we need to give it plenty of stick to hold onto. So the stick needs to go all the way through.
Okay! I'll see if my husband can yank out the handle and I'll carve a longer peg on the handle and drill a deeper hole. (We had to yank the handle out once already because the handle split. I carved a new handle and inserted it.)
(My husband kept telling me, too, that I should have gone all the way through, but I interpreted "through" as meaning "into," rather than "all the way through")
I made it all the way through! (Man, it was HARD drilling through that last bit with the giant drill bit. It kept getting stuck, and since there was no handle to hold, I had to keep undrilling it and cleaning the hole and starting again, only to get 1/2 crank before having to take it out again. I definitely need a hand drill!)
Paul, just to throw a wrench in the works... I found this video last night, which is a "ready-made" mallet cut from a tree whorl with the trunk as the head and a branch for the handle.
It seems to fall in the middle between the club mallet and the compound mallet, as far as skills and construction, but sure seems pretty darn Permie to me! Also sort of in the same vein as the coat hooks...
